Patent GB-377405-A (GB)
Title: Improvements in and relating to printing presses
IPC: B41F13/02
Filed: 1931-07-07
Abstract: 377,405. Feeding webs. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and POOL, W. J., Chelmsley, Barley Lane, Hillmorton, near Rugby. July 7, 1931, No. 19575. [Class 100 (i).] In an arrangement for controlling the feed of a web 1 with the aid of mechanism automatically effective to advance or retard the web whereby it is maintained in register with other webs, an independently-operable adjusting-device is provided, comprising a manually-operated shaft 39 and worm 38 mounted in a carrier 37 fixed to a shaft 35 and meshing with a sector 36 loose on the shaft 35. The sector 36 also gears with a worm 40 mounted on a shaft 41 which is automatically rotated in the appropriate direction to maintain the web in register by means such as the photo-sensitive device described in Specification 373,189, which operates to drive the motor 29 and thereby adjust the driving- belt 12 of the feed-roll 3 and also rotate the worm 40. The latter drives the sector 36 and thereby the carrier 37, which is effectively locked thereto by the worm 38, and the shaft 35, to adjust the position of a roller 14 which is mounted on arms 22 carried by the shaft 35 and over which the web is passed, and thus effect a backwards or forwards displacement of the web. Rotation of the hand-member 39 similarly serves to adjust the position of the roller 14 and thus of the web, the sector 36 being effectively locked by the worm 40. Stops 36a on the sector 36 limit the extent of this correction so that a definite residual movement of the roller 14 is always possible by the automatic device.

Title: Process for the manufacture of burnt building materials or the like from clay
IPC: C04B33/02
Filed: 1925-08-04
Abstract: 238,229. Gr÷nroos, H. Aug. 6, 1924, [Convention date]. Making bricks and tiles; pottery materials.- Ordinary non-refractory building bricks produced from clay are made by a continuous process, without air-drying prior to firing, by burning or sintering a portion of the clay at a comparatively low temperature and using the powdered burnt product to mix with the remaining clay to form the moulded bricks. If the clay does not fuse or sinter at a low temperature, compounds of sodium and potassium together with iron oxide may be added to reduce the fusing temperature. As an example, 10 kilograms of the following mixture, burnt at about 800‹ C.,may be added to 1000 kilograms of raw clay :-200 kilos. of burnt and pulverized clay, 100 kilos. of burnt and pulerized cryolite, 10 kilos. of iron oxide, mixed with 400 kilos, of water to form a liquid mass for kneading with the main bulk of clay.

Abstract: 1,126,670. Aerials. ROHDE & SCHWARZ. 28 April, 1967 [29 April, 1966; 2 Aug., 1966], No. 19704/67. Heading H4A. An aerial comprises a ring-shaped main reflector 1, 2, Fig. 1, the surface of which is formed by the rotation of a parabola or other conic section about a central axis 3 which is parallel to the tangent at its vertex, a centrally disposed feed 6, a Cassegrain-type sub-reflector ring 8 (shown partly broken away), the surface of which is formed by the rotation of a curve, such as a hyperbola, about the axis 3. A plastics or other radiation transparent mast 4 supports the halves 1, 2 of the main reflector, said halves being interrupted over a central section 5 to permit radiation from the feed 6 to pass through to the sub-reflector 8. The said sub-reflector, which is con-focal with the main reflector, is supported therefrom by stays 9. The feed 6 may be a bi-conical aerial, or it may be constituted by crossed log-periodic aerials, or other omnidirectional aerial arrangements. In a second embodiment, the feed is a directional horn (16), Fig. 2 (not shown), which radiates upon a portion only of a sub-reflector ring (8), and scanning is effected by rotating said horn. Phase correction by means, for example, of a lens may be provided in the horn. In a third embodiment, a main reflector 1, Fig. 3, is formed as a half paraboloidal ring by division in a horizontal plane and is provided with an additional inner paraboloidal ring 11 which receives radiation directly from a feed 16, and projects it upon a sub-reflector ring 8.

Anadvertisingapparatus comprises a non-spherical body of revolution 14, a closed track 3, means for keeping the body in position relative to the track so that the body appears to be substantially tangent to the track and means 7, e.g. an electric motor hidden from an observer for driving the body along the track the surface of the body being such that the body seems to roll along the track when it is in movement under the impulse of the driving means. One or more additional bodies such as 15 may be fixed to the body 14. As shown the bodies 14, 15 are rings which are welded together, the lower ring 14 being also welded to an arm 12 which projects from a turntable 11. The weight of the rings is balanced by a counter-weight 13 and the turntable is rotated by the electric motor 7. The junction of the ring 14 and arm 12 is positioned on the track 3, which is a circular slot, in a casing 1 which conceals the turntable and motor, so that the illusion is given that the ring 14 rolls round the track, with the ring 15 rolling on the .ring 14.

Filed: 1951-08-25
Abstract: 697,563. Rotary burners. RAY, W. R. Aug. 25, 1951, No. 20080/51. Class 75(i) In a rotary burner the fuel is delivered centrifugally to an inverted rotary cup 27 and projected centrifugally in an atomized spray from under the rim 73 thereof towards the circular side wall of a motor-driven rotary bowllike combustion chamber 11 within which the cup 27 is mounted and to which combustion air is delivered. As shown the combustion chamber 11 has a heat-insulating jacket 12, 14 and is secured to an air tube 17 which extends into the chamber 11 and is fixed to a collar 18 screwed on the top of a hollow shaft 19 of a motor 20. The shaft 19 is extended within and beyond the tube 17 by a member 24 which has an upwardly diverging bore 25 terminating in radial spill pipes 30 and is apacedly surrounded by a tubular jacket 26 which carries the inverted cup 27. A blower 22 is mounted on the shaft 19 to - revolve in a casing 45, 48 to which air is .supplied, via an annular chamber 34 arranged therebelow, from an adjustable intake duct 62, 63. To heat insulate the motor 20, the annular chamber 34 surrounds a lubricating oil chamber 56 in which the motor 20 is housed, a hole 58 in the motor casing providing for access of the oil to the motor bearings. Fuel is supplied to the hollow shaft 19 from a constant level reservoir 67, via a throttle valve 66 and a bellows seal 42 at the base of the shaft. In operation fuel thrown from the radial feed pipes 30 passes through a blow-back preventing wire mesh screen 31 onto the sides of the inverted cup 27 and thence under the rim 73. towards the side wall of the chamber 11. Air supplied by the blower 22 passes via holes 50, 71 and 72, through the air tube 17 into the cup 27 and chamber 11, secondary combustion air passing via holes 74 and an annular member 51 surrounding the chamber 11 to a combustion ring 52. The combustion chamber 11 has an annular rib or baffle 77 on its side wall and an inturned lip 78 to retard the upward passage of the burning mixture and thereby ensure complete combustion.

Abstract: 224,015. Baumann, E. Aug. 15, 1923. Screwing; tapping; taps. - Screw-threads are cut by a process wherein the whole thread is cut simultaneously in one working course, the feed movement of the dies being substantially in the direction of the side of the thread. The dies 2 are mounted in a head 1 secured to a square shaft 4 which is mounted in bearings 5 and is moved longitudinally by means of a cam 9 on a shaft driven from a belt-pulley 17 through changegears 16 and worm gearing 15. During the threading operation the dies 2 are moved radially by means of a tapered mandrel 3 which is moved axially by means of a cam 12. The axial and radial movements are so related that the dies cut into the work in the manner indicated in Fig. 6 only one face of the screw-thread being worked. The work-piece 18 is held in a chuck 19 which is driven through bevel-gearing 21, 23 from the pulley 17, the chuck holder 25 being angularly adjustable for cutting conical sleeves &c. In a modification, the tool may have the rotary movement instead of the work. In a further modification, Figs. 7 and 8, the cutting dies are mounted in levers 32 pivoted at points 30 in advance of the cutting edges and the radial adjustment during cutting is effected by wedge members 35 acting against springs 34.
